ORE-SEPARATOR.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed. June 26, 1906. Serial No. 323,476.

To all whom it may concern:

Be it known that I, ELMER A. Boss, a citizen of the United States, residing at Ticonderoga, in the county of Essex and State of New York, have invented a new and useful Ore-Separator, of which the following is a specification.

. This invention relates more particularly to means for separating finely comminuted ores, but can be employed for other purposes.

The principal object is to provide a novel and exceedingly simple structure that can be continuously operated and will effect the complete and proper separation and grading of the ore delivered thereto, said structure automatically discharging the different grades as predetermined quantities thereof accumulate.

In the accompanying drawings :Figure 1 is a side elevation of one embodiment of the invention. Fig. 2 is a longitudinal sectional view on an enlarged scale through a portion of the same. Fig. 3 is a detail sec- Fig. 4 is a side elevation of a slightly modified form of construction.

Similar reference numerals designate corresponding parts in all the figures of the drawings. X

In the embodiment illustrated in Figs. 1, I 2 and 3, the structure consists of a plurality of separating units and to this end a substantially horizontally disposed separating conduit is employed, comprising sections 5 1 and 6 of different diameters, said sections being arranged end to end and detachably fastened together, as shown at 7. It will of course be understood that while two sections are shown, any number may be employed, as desired. Connected to the outer end of the smaller section 5 is a T-coupling 8, the upright arm 9 of which constitutes the means of communication between the lower end of a feed hopper 10 and the conduit section 5. One of the horizontal arms 11 is bolted to the section 5, as shown at 12 ,the other arm 13 constitutes a nozzle, which is connected to a motive fluid supply pipe 14. This supply pipe extends from any suitable source, and may be employed for conducting either water, air or other suitable fluid, air being perhaps preferably employed in mech anism of this character. The nozzle 13 terminate's in a tapered wall 15, which, as

shown in Fig. 2, constitutes a deflector for directing the material from the hopper rearwardly of said nozzle. A turning valve 16, located in the nozzle, is provided with a wall 17 that is movable across the nozzle and coacts with the wall to vary the area of the discharge orifice of said nozzle. It will be noted that this valve and deflector wall direct the air current longitudinally through the upper portion of the conduit. A gate or valve 18 controls the supply of material from the hopper to the conduit.

A plurality of depending outlet pipes 19 have their upper ends communicating with the lower side of each conduit section, said pipes preferably consisting of sections 20 connected by couplings 21. The lower ends of the pipes of each set, communicate with downwardly inclined collector pipes 22, constituting a common receiver, which terminates in a lower discharge spout 23. A suitable conducting conduit 24 may be connected to each discharge spout 23. The passageway through the discharge s out 23 is controlled by an automatic valve 25 that is mounted on the inner end of a lever 26 fulcrumed upon a' link 27 suspended from one of the collector pipes 22, as shown at 28. The outer arm of this lever has a counterweight 29 adjustably mounted thereon, which weight constitutes means for yield ingly resisting the opening movement of the valve, as will be evident by reference to Fig. 2. The discharge end of the larger conduit section 6 communicates with a tailings re ceiving hopper 30, which hopper has a depending discharge spout 31, and a suitable screened top 32.

The operation of the structure may be briefly described as follows. Air or other motive fluid under pressure, being delivered through the pipe 1 1, will discharge longitudinally and successively through the conduit sections 5 and 6. The amount of discharge is limited by the turning valve 16. The pressure will be considerably greater in the section 5 than in the section 6, because of the larger diameter of the latter. If now finely coinminuted material is placed in the hopper 10 and allowed to gravitate downwardly through the spout 9, it will be caught by the discharging current of fluid, and driven longitudinally through the separating conduit. The heavier particles will drop in the section 5, and gravitate down the pipes 19 to the common receiver. The particles of an intermediate weight udll pass through the conduit section 5, but because of the less force of the motive fluid in the conduit sec tion 6, they will gravitate to the bottom of the same and escape through the set of pipes communicating therewith. T he lightest particles will be delivered into the tailings receiving hopper 30, which permits the escape of air or other motive fluid through the top and allows the particles to gravitate through the spout 3].. llhen suitlicient material has accumulated in the collectors or receivers, to overcome the weights 29, the valves 25 will open and permit the automatic discharge of the collected material.

A slightly modified form of construction is shown in Fig. 1. The conduit sections 5 and 6 of different diameters are employed, as is also the nozzle l3 with a feed hopper 10v A tailings discharge hopper corresponding in all respects to the hopper 30 above described is connected to the discharge end of the larger separator section 6. Sets of depending outlet pipes 19 are also connected respectively to the conduit sections 5 and 6, but these spouts in this particular embodiment deliver into hoppers 22 havingdischarge spouts controlled by automatically opening valves 25 similar to those already described. .t will be apparent that this structure operates in the same manner as that already described, and has all the advantages of the same.

From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted .to without departing from the spirit or sacrificing any of the ad vantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a separator of the character described, the combination with an elongated l i l conduit having a plurality of sections, each section having discharge means comprising portions downwardly converging into a sin gle conduit, and secondary discharge pipes connecting successive portions of the first mentioned conduit and the dowirardly converging portions.

2. In a separator of the character described, the combination with an elongated classifying conduit having a plurality of sections, each adapted to collect a separate grade and each provided with discharge means comprising pipes converging downwardly into a single conduit, secondary dis charge pipes connecting the classi; mg conduit and the converging pipes, and means for forcing fluid and suspended solids through the classifying conduit.

3. In a separator of the character described, the combination with a substantially horizontal separating conduit having a series of outlets in its bottom, of feeding means having a discharge port communicating with the upper side of the conduit, a motive fluid supply nozzle connected at one end to the conduit adjacent to the feeding means and including a rearwardly tapered deflector wall extending into the upper part of the conduit at the port and having a downwardly inclined upper face that projects partially across the port, said wall having: a valve seat in its under side, and a turning valve located in the nozzle below the de fiector wall and engaged in the seat, said valve including; a wall movable across the nozzle toward and from the under side of the tapered wall and at an inclination thereto to vary the area of the nozzle and direct the air longitudinally through the upper portion of the conduit, across the discharge port and above the outlets.

In testimony, that I claim the foregoing as my own, I have hereto aillxed my signature in the presence of two witnesses.
